Hi All,
Why in the kamailio 3.1.2 I have to give a sip_msg parameter to function register_tmcb when I want register a function of my module with TMCB_RESPONSE_OUT parameter? I can't understand this behavior...
the callback is for specific transaction, which is created by t_relay() (or other tm functions such as t_newtran()). At the moment a module registers a callback, the transaction may not be created yet, so giving the sip message it required to build a list callbacks attached to message id -- once the transaction for that request is created, the callabacks list will be linked to it.
Is it any problem to give this parameter? you should have a valid sip msg structure in your functions exported for config usage.
